    Somewhere in the ymc suite there's a philosophy: numbers should travel as strings, because strings are what survive round-trips through prompt builders and text fields. Is round to x is that philosophy made visible - it takes two text inputs and outputs whether one rounds to the other, as a "True"/"False" string. It's a comparison node that never asks you to touch a BOOL socket.

    Where does that get you? Text-driven conditionals. If your seed, your batch counter, or some prompt-extracted value lives as a string, this gives you a gate without a cast: compare text against isRoundTo, and pipe the resulting boolean-string into the string-switch variant (switch a and b (isRoundTo)) to pick between two prompts. It's niche, but it's the missing connective tissue between "everything is text" and "I need to branch."

    How it works

    The comparison is deliberately fuzzy: both values are converted with int(round(float(value))) and then compared for equality. So "0.8" with isRoundTo = "1" returns True (0.8 rounds to 1), and "0.4" against "1" returns False. That "rounds to" behavior is why it's not a plain equals node - it's asking whether text lands in the rounding bucket of isRoundTo, which is exactly the question you'd want for a noisy numeric source like a weighted score or a scaled value.

    One implementation wrinkle: the inputs are named text and isRoundTo on the surface, and the output is a single STRING named boolean carrying "True" or "False".

    Inputs and outputs

    • text - the value under test, default "1"
    • isRoundTo - the target value, default "1"
    • Output: boolean - a STRING, "True" or "False" (note: a string, not a BOOL, so don't wire it into a node that demands a real boolean)

    Installing it

    # ComfyUI Manager: search "ymc suite" and install ymc-node-suite-comfyui
    # or:
    cd ComfyUI/custom_nodes
    git clone https://github.com/YMC-GitHub/ymc-node-suite-comfyui
    

    Restart after installing. Four tiny pure-Python PyPI helpers self-install; no models, no GPU cost.

    Gotchas

    • The output is text, not a real boolean. Feed it to switch a and b (isRoundTo), which does the same rounding comparison internally, or to something that accepts a "True" string - don't assume an implicit cast.
    • Because it rounds, "1.4" vs "1" is False while "1.5" vs "1" is True (Python rounds half to even, so 1.52). If you wanted strict equality, this is the wrong tool.
    • It's in ymc suite/text/plain, next to to number - if you find yourself casting to number just to compare, this node is the shortcut that skips the cast.
